This RFC patch-set introduces the ZIO framework for input/output,which will be used in the new series of drivers by the BE-CO-HTgroup at CERN.

The use-case it is meant to cover is very fast I/O withhardware-provided timestamps. The first production driver we willsupport is a 100Ms/s 4-channel 14-bit ADC (developed on ohwr: seehttp://www.ohwr.org/projects/fmc-adc-100m14b4cha ). We need similarbandwidth on output.
